Claims. (Cl. 7689.2)

This invention relates to razor blade sharpening devices.

It is an object of the present invention to provide a razor blade sharpener that will sharpen all types of razor blades such as single edge, double edge and straight edge blades, and wherein the razor edge is sharpened without employing the usual methods of grinding and honing.

It is another object of the present invention to provide a razor blade sharpener which is self-lubricated, is clean and free of dust or the like while not in use, and wherein there is provided such a device of relatively small compact design of low cost and long life.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure l is a front elevational view of a preferred embodiment of the present invention shown in operative use;

Fig. 2 is a front elevational view shown partly in section of the invention when not in use;

Fig. 3 is a vertical sectional view taken along the line 3-3 of Fig. 1;

Fig. 4, is a horizontal sectional view taken along the line 4-4 of Fig. 3; and

Fig. 5 is a view similar to Fig. 4 of a modified form of the present invention.

Referring now more in detail to the drawing, 16 represents a container of plastic or other suitable material closed at the bottom and having an internally threaded inverted open upper end, substantially as illustrated.

An externally threaded closure 11 is provided and is adapted to be screwed into the open upper end of the container 10, being integrally formed with a flange portion 12 adapted to fit about the open upper end of the container, when screwed therein.

The closure 11 at one end is integrally formed with the reduced extension 13 into which is molded or otherwise secured a pair of juxtaposed, substantially rectangular plates 14. The plates or jaws 14 are formed of hardened steel and are provided on their adjacent faces with the intermeshing alternating grooves and ridges 15 (Fig. 4). The upper ends of the jaws 14 are bent outwardly (Fig. 3) to provide a groove of V-shaped cross section, having a zero apex 16.

The container is filled with the lubricant 17. It will be noted that the jaws 14 are designed to present a reversed curve apex (Fig. 4). When assembled, as shown in Fig. 1 the container provides a handle for the device, as will be obvious. In storage, the closure 11 is reversed (Fig. 2) and screwed into the container 10 with the jaws 14 being received within the lubricant 17, which latter is necessary for the sharpening process of the jaws.

In operation, with the device assembled as shown in Fig. 1, the razor edge 18 of the razor blade indicated generally at 19 is drawn across the apex 15. This action reforms the curled edge of the razor blade 19 back to its original shape, thus sharpening the same. The lubricant 17 prevents chafing 0f the razor edge, thus allowing the deformed edge to take its original normal position.

It should now be apparent that there has now been provided a device for razor blade sharpening employing a new principle, namely that of reforming the edge rather than honing or grinding the same. It should also be apparent that there has also been provided a device at an extremely low cost which is small, of compact design and which is kept clean and free of dirt or dust in storage, yet is ready for instant use. It should also be apparent that there has been provided a device of the above type which is protected from dust or corrosion while stored.

Referring now particularly to Fig. 5, there is shown a modified form of the present invention wherein the jaws 14a are provided with juxtaposed planar surfaces, thus providing a straight line zero apex 15-a. In other respects, the form of the invention shown in Fig. 5 is the same as that shown in Figs. 1 through 4, and like reference numeral indicate like parts throughout the view.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.

What we claim as new and desire to protect by Letters Patent of the United States is:

1. A razor blade sharpening device comprising a container open at one end, a reversible closure for said container, and a pair of hardened steel, juxtaposed jaws mounted within one end of said closure, said jaws at their ends remote from said closure being curved outwardly and away from each other whereby to provide a groove of V-shaped cross section having an apex adapted to receive therewithin the edge of the blade being sharpened while being drawn thereacross, said container containing a lubricant to prevent chafing of the blade whereby to sharpen the blade by reforming the edge rather than by honing or grinding the same.

2. A razor blade sharpening device according to claim 1, the juxtaposed adjacent surfaces of said jaws being provided with intermeshing, alternating ridges and grooves whereby to provide an apex of wave shape.

3. A razor blade sharpening device according to claim 1, adjacent juxtaposed surfaces of said jaws being planar whereby to provide a straight line apex.

4. A razor blade sharpening device according to claim 1, said container having an internally threaded open end, said reversible closure being externally threaded and having a flange adapted to abut the open end of the container when said closure is screwed therein.

5. A razor blade sharpening device according to claim 4, said closure at one end being formed with a reduced extension, said jaws being mounted within said extension and being adapted to be immersed in the lubricant when said closure is reversed.
